Hospitals and health systems are entering 2026 under sustained financial pressure. Margins remain historically thin, labor and supply costs continue to rise, and revenue cycle teams are being asked to manage growing complexity with fewer internal resources. At the same time, payer behavior is becoming more volatile, liability-driven claims are increasing, and cash predictability is harder to maintain.  

Against this backdrop, the cost of not managing revenue leakage has become far more material. What were once considered edge-case billing scenarios — motor vehicle accidents, workers’ compensation, and other non-traditional claims — are growing in both frequency and financial impact. While these claims still represent a relatively small share of overall volume, their contribution to aged A/R, working capital drag, and compliance exposure is increasing year over year.

At the same time, there’s a clear shift underway in how leading health systems are thinking about complex claims. Manual workflows, fragmented follow-up, and generalist teams are being replaced by specialization, automation, and AI-driven intelligence. The goal is no longer just recovery. It’s early identification, faster resolution, correct sequencing, and predictable cash flow. Complex claims are being treated not as exceptions, but as a distinct revenue stream that requires purpose-built technology and expertise to manage effectively. 

That shift is reshaping how organizations think about complex claims — and why addressing them now has become a strategic financial priority, not an operational afterthought. 

 

What are complex claims?

Complex claims are non-traditional payer claims that fall outside standard commercial and government billing workflows. Most commonly, motor vehicle accident (MVA), workers’ compensation (WC), and Veteran Affairs (VA) fall under this category.  

Unlike typical health insurance claims, where coverage and payer responsibility are usually established at or before the point of service and only two parties are involved, complex claims often require post-discharge investigation to identify the responsible payer, open or verify a claim, confirm benefits, and gather the right documentation. 

They frequently involve multiple stakeholders: patients, employers, carriers, adjusters, attorneys, and third-party review firms, and they are highly sensitive to coordination of benefits (COB) sequencing and compliance rules. 

The core issue: small volume, outsized impact 

According to a recent HFMA Payment Variance Report, complex claims typically account for ~3–5% of claim volume, yet represent ~15–20% of receivables, meaning they can disproportionately inflate A/R and working capital drag even when overall performance looks stable. 

And it’s not only a cash problem. Complexity also creates: 

• More touches per account 

• More rework loops 

• More room for sequencing and documentation errors 

• More exposure to compliance and litigation risk 

These complicated billing scenarios don’t overwhelm you with volume. They overwhelm you with time, aging, and risk. 

 

Why complex claims distort A/R and forecasting 

Complex claims often become the long-tail inventory in A/R – the accounts that sit in the 120+ and 180+ day buckets and make cash forecasting harder. Why? 

1. They’re discovered late (often after discharge) 

Unlike standard commercial workflows (where coverage is usually confirmed at or before the point of service) MVA and Workers’ Compensation claims frequently require post-discharge discovery. Teams may need to contact patients, employers, carriers, adjusters, attorneys, or third-party administrators to establish the correct payer path. 

2. They have longer, more variable resolution cycles

Complex claims can take 60-90 days longer to resolve than standard claims. For some categories like Veteran Affairs and motor vehicle accidents, average claim processing times can take 130-150+ days, according to recent news reports. 

3. More intermediaries are involved (and accountability gets clouded)

In motor vehicle accidents and workers’ compensation, many payers use bill repricing and payment review firms between the provider and the carrier. That can add review layers, create opaque reductions, and delay payment while the provider tries to validate methodology and negotiate resolution 

 

The shift to automation and AI as a turning point for complex claims 

In 2025 and into 2026, health systems are increasingly recognizing that manual processes and traditional exception handling aren’t sufficient to manage the growing complexity of claims — not just in volume, but in financial impact. Leading revenue cycle leaders now view automation and artificial intelligence (AI) as essential tools to reshape workflows, reduce friction, and accelerate payment outcomes. 

According to recent industry research, 90% of healthcare revenue cycle leaders plan to invest in AI and automation within the next two years, underscoring a widespread strategic shift toward technology-enabled processes rather than incremental people-based scaling. Major associations like the American Hospital Association also highlight how AI and automated workflows can lower denial rates and improve operational efficiency in claims management. 

The rationale is clear: automation and AI don’t just speed up routine tasks. They enable revenue cycle operations to anticipate issues before they escalate into aged A/R, optimize payer sequencing, and free specialized staff to focus on exceptions that truly require human judgment. In this evolving landscape, technology is no longer an optional add-on. It’s a foundational capability for any health system aiming to stabilize cash flow and reduce variability in revenue outcomes. 

 

Transforming complexity into a controlled revenue stream 

Complex claims require an advanced level of specialization, legal awareness, modern technology, and payer intelligence that most revenue cycle teams were never built to sustain at scale. 

That’s where Revecore comes in. 

Revecore was purpose-built to manage the small slice of claims that behave differently — motor vehicle accidents, workers’ compensation, and VA claims — with discipline and accountability. Rather than treating these accounts as a secondary queue or an exception process, Revecore operates complex claims as a dedicated revenue stream with specialized teams, proprietary technology, and built-in compliance safeguards. 

Our approach combines: 

• Deep domain expertise across Auto/TPL, Workers’ Compensation, and VA claims — including legal and regulatory knowledge most hospitals can’t staff internally 

• Purpose-built technology and automation, including 80,000 workflow rules, that identifies complex claims early, discovers coverage faster, enforces correct billing order, and prevents claims from stalling in aged A/R 

• Proven recovery performance, delivering materially higher reimbursement, faster cash acceleration, and meaningful reductions in 120+ and 180+ day A/R 

• Outcome-aligned economics, with contingency-based pricing that ties our success directly to yours 

The result is predictability where there used to be drag. Complex claims move faster, resolve more cleanly, and stop distorting A/R and cash forecasting. Internal teams regain capacity. Compliance risk is reduced. And revenue that once quietly aged out becomes recoverable.

In 2025 alone, Revecore recovered $1.8 billion on behalf of our clients, resulting in 50-70% faster cash flows on average compared to in-house teams.  

When complexity is the challenge, specialization outperforms scale. Revecore exists to master that complexity and turn it into controlled and measurable financial performance.
